ADAM O. HENDRIOKS,OF DUFFIELDS, ASSIGNOR OF ONE-HALF TO HENRY ST. JOHN SHEPHERD, OF SHEPHERDSTOWN, WEST VIRGINIA.

FERTILIZING SPECIFICATION forming part of Letters Patent No. 272,547, dated February 20, 1883. Application filed September 19, 1882. (No model.)

To all whom 'it may concern Beit known that 1, ADAM C. HENDRIcKs, of Duffields, in the county of Jefferson and State of West Virginia, have invented certain new and useful Improvements in Fertiliziug Grain-Drills; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to 1 o make and use the same, reference being had to the accompanying drawings, which form a part of this specification. y

My invention consists of certain improvements in grain-drills, the chief feature. ot'

.15 which is the arrangement ot' three sprocketwheels with chain thereon for operating either or both divisions ofthe grain-shaft, and also either or both divisions of the fertilizershaft from the axle of the traveling wheels.

In the drawings, Figure l is a detached view of the axle ot' the traveling-wheels with sprocket-wheel and clutch thereon. Fig. 2 represents the rock-shaft and cranklever for elevating the boots, and also the axle of the traveling wheels and part of the frame. Fig. 3 is an end view of rock-shaft and lever, Fig. 2. Fig. 4 represents a ratchet and pawl or clutch connected with the hub of the traveling wheel. Fig. 5 represents the divided 3o grain-shaft and its connection with other devices. Figs. 6 and 7 aresectional views representing the three sprocket-wheels, one on the axle of the traveling wheels, another connected with the grain-shaft, and the third connected with the fertilizer-shaft, all gearing with the chain, by which motion is transmitted. Fig. 8 is a bottom view of the ceutral portion ofthe machine herein described. Fig.9 represents a modification of the clutch 4o shown iu Fig. 4. l

My improvements may be applied to a fertilizing grain-drill of the ordinary construction, which need not be described. vThe hopper has a graimdivision, W, and a fertilizerdivision, Y, as seen in Figs. 6 and 7. Across the middle of the hopper is made a box with hinged covers fi i', Fig. 7 to receive the sprocket-wheels B and O with chain D thereon, and also to exclude dust and allow access l to the central gearing for the purpose of oil- 5o ing the same. The sprocket-wheel Ais attached to the axle E of the traveling wheels, and by means of chain D transmits motion to the sprocket-'wheel B upon ashort central hub or shaft, R, of the grain-shaft and also to the sprocket-wheel Cof the central hub of the fertilizer-shaft. This chain is provided with au idler, f, Fig. 7, in the usual way. Between the two divisions R and E of the grain-shaft is va short hub or shalt, R, Fig. 5, with a 6o clutch on each end arranged to be thrown into gear or out of gear with the two divisions R and It of the grainshaft by means of the clutch-rod m and lever M, Figs. 5 and 8. In the same manner the two divisions of the fertilizershaft are. arranged to be thrown into gearor out of gear, so that either division thereof or both divisions of said shaft may be set in motion or stopped at pleasure. Each hub S of the traveling wheels is also provided 7e with a clutch, L, and spring-pawl K, Fig. 9,

so that said axle may be thrown o-ut of gear with said wheels, and thus stop the motion of chain'D at pleasure.

g Having described my machine, what I claim 1s- 1. The described combination ot' three sprooketwheels A B C and chain D, with devices for operating the divided grain-shaft and divided fertilizer-shaft from the undivided axle 8o of the traveling wheels, substantially as set forth.

2. The combination, in a. grain-drill hopper divided transversely, of a hinged covered box centrally located therein, extending from side to side land from. top to bottom thereof, in w hich are journaled the sprocketwheels mounted on their respective shafts, whereby vthey are kept free from foreign substances and access is had for the application ot' lubricants, 90 as described and shown.

In testimony that I claim the foregoing as myown I have -hereto afxed my signature in presence of two witnesses.
